how to group a list of dates by year and then by month?
You can add further groups by adding closures to the groupBy call. Calendar's MONTH is off by one (starts at 0), so add one there. Next you want to fill all month with the count, which is the size() of the group by results. This will be collected over 1..12 for each month (proper order and null for the missing groups). def date = new Date() def dates = [date-350, date-400, date-300, date-50, d

Gradle plugin best practices for tasks that depend on extension objects
I'd look at this problem another way. It seems like what you want to put in your extension is really owned by each of your tasks. If you had something that was a "global" plugin configuration option, would it be treated as an input necessarily? Another way of doing this would have been to use your own SourceSets and wire those into your custom tasks. That's not quite easy enough yet, IMO. We'

How to use logger in Groovy with soapui?
I don't think this error has anything to do with Log4J. I don't know what Soapui is, but judging by the error message, it appears your class is expected to have a main method. What happens if you add this method to Log4jLoggerClass? static void main(String[] args) { println "main method invoked" } Update In response to your comment below, I guess the reason you're not seeing any logs on the

Is it possible to set accent colors for pptx4j in groovy?
I think you want to change the a:accent1 element in your theme part (or one of your theme parts), for example: <a:theme name="Office Theme"> <a:themeElements> <a:clrScheme name="Custom 1"> <a:dk1> <a:srgbClr val="2F2B20"/> </a:dk1> <a:lt1> <a

Lazy evaluation of chained functional methods in Groovy
Adding the suggestion as an answer taking cfrick's comment as an example: @Grab( 'com.bloidonia:groovy-stream:0.8.1' ) import groovy.stream.Stream List integers = [ -1, 1, 2, 3, 4 ] //.first() or .last() whatever is needed Stream.from integers filter{ it > 0 } map{ it * 4 } filter{ it < 15 }.collect() Tim, I still know what you did few summers ago. ;-)

Retrieve all jenkins parameters to iterate in groovy code

This code can correctly read the Environment variables that are set in any Jenkins job: import jenkins.model.Jenkins def thr = Thread.currentThread() def build = thr?.executable def env = build.getEnvironment() def buildNumber = env.get("BUILD_NUMBER") In case you want to read the Build Par

Equivalent of perl diamond/python fileinput in groovy?
def inputs=[]; Only practical way is to have collection "similar objects". In this case having a collection of InputStream would do if(args.length==0) { inputs.add(System.in) } else { args.each { inputs.add(new FileInputStream(it)) } } inputs.each { (it).eachLine { line -> println(line) } }

Weird NullPointerException in Groovy inject
Because this code: if (!conf.contains('homepage')) { list << conf.trim() } does not return anything when the condition is not met. There's no else to this if. If you add an else returning a meaningful value, you'll avoid the exception. The ternary operator, on the other hand, does return a value whether or not the condition is met so this code: conf.contains('homepage') ? list : list &l

*in* keyword with String in Groovy
The in keyword works on Collection types; not on String types. Why does String to String Comparison work? Groovy in operator depends on the isCase method. It will use that in comparison. The String isCase method uses equals to perform this comparison. Obviously hello is not equal to hello world, ergo it returns false. However, hello does equal hello, ergo true.
